The top of the cylinder at 35 may also as a stand through which the entire de be termed ornamentally to give a pleasing 1 and allowing the liquidin the pipe 23' to fill 7 appearance to the device and if desired an electric light, 36 or other ornament may be placed on the top of the same for advertising or display purposes. The piston 22 may be packed with suitable packing material or the same may be provided with a number of piston rings 37 extending around the periphcry of the same engaging the walls of cylinder 21 to form a liquid-tight connection between the walls of said cylinder and the surface of the piston. Piston rod 31 is formed with a shoulder at which engages the underside of piston and passes directly through the same where it is secured thereto by means of a nut 39 engaging a tin-ended. end 40 of said rod.

The valve mechanism 26 which controls the flow of liquid to and from cylinder 21 is best shown, in Figure l and comprises primarily a casting 44 which is bolted to the underside of casting 24 by means of bolts 45. Casting 44 is formed with a cylindrical bore 46 extending longitudinally and in a horizontal direction through the same. A cylindrical slidable valve member 47 is mounted in this bore and is provided at its ends with two .stufiing boxes 48 and 49 which are screwed into the ends of casting 44. A pair of ports. 50 and 51 extend through casting 24 and the castim 44 both communicating with the interior or the cylinder 21 below the piston These ports pass through the bore 46 within the casting 44 and are adapted to alternately register with a pair of ports 52 and 53 formed in the slidable valve member 47, so as to complete the passageway from the cylinder 21 through the castings 24 and 44 w ien said valve member 47 is properly positioned in relation thereto. To the underside of the casting 44 is bolted a cap 54 which is formed with a nozzle having a hose connection 56 and provided with an internal passage-way 57 communicating with the port 51. The hose 27 is fixed to the-hose connection 56 by means of a clamp 58 whereby liquid may be removed from the cylinder 21 therethrough when the valve member 47 is in the position indicated in Figure 1. Registering with the port 50 in casting 44 is formed a port 59 in cup 54 which has screwed into it a bent nipple 60 connected to the pipe 23 by a common union 61. When the valve member 47 is slid along the bore 46 so that port 52 registers with the port 50, direct communication is had between the liquid reservoir and the interior of cylinder 21 below piston 22 through pipe 23 and said ports. A compression coil spring 62 extending around a lug 63 formed on casing 20 and around a similar lug 64 formed on the end of valve member 47 and seated against the end of said valve member 47 and casing 20 normally holds this valve member in the position shown in F igure 1, in which position the flow of liquid through the pipe 23 is checked while the flow of liquid from the cylinder 21 through the hose 27 is permitted.

For holding the valve. member 47 in its two positions I employ a device which comprises a portion of the controlling mechanism 30 and which is clearly shown in Figures 3, 4, 5, 6 and 7. The extreme end 65 of valve member 47, indicated in Figure 7, is formed flat and has pivoted to it a. forked rod or bar 66 by means of a pin 67 which pass-es directly through said flattened portion 65 and the forked end 68 of said bar 66 and extends beyond said forked portion 68 on both sides thereof. Bar 66 as shown in lfi igure 4, is slidable between two guides ()9 and 76 issuing upwardly from a lower arm 71 of an angular bracket 72 bolted to the underside of casting 24 by means of a cap screw 73 screwed into said casting 24 and passing through a lug 75 formed on said bracket. The bar 66 is formed with. two shoulders 76 and 77 each of which is adapted to engage a fixed projection 76 issuing from the upper surface of the arm 71 of bracket 7 2 to hold the valve member 47 in either of its effective positions against the action of spring 62. In Figure 4 and Figure 5 the bar 66 is shown with the shoulder 7 6 engaging projection 78 in which position of valve member 47 passage of liquid through the hose 27 is permitted. In Figure 3 bar 66 is shown. with the shoulder 77 almost in a position to engage projection 78. hen said shoulder in engagement with the projection 78 it can readily be comprehended that port 52 is in alinement with port 50 which permits flow of liquid into the cylinder 21 through pipe 23 and cuts elf the flow of liquid through the hose 27.

For moving valve member 47 against the action of spring 62 I provide a device best shown in Figure 1. An angle iron support 7 9 extends across the casing 20 and is secured thereto. This support has attached to it a lug 83 to which is pivoted a swinging arm 80 at 84 which extends upwardly and is provided with. a forked head 81, formed with a longitudinal slot 82 on both of the forked portions thereof, adapted to engage the protruding ends of the pin 67 which, as before men tioned, pivotally connects bar 66 to the valve member 47. Between the pin 67 and pivot 84 on arm 80 is provided an eye bolt 85 which passes through said arm and is provided at it. end with a nut 86 by means of which the position of the same may be adjusted relative to the arm. This eye bolt has attached to it a cable 87 which passes over a pulley 88 mounted on an angle iron support- 89 which extends across the casing 20 and is secured thereto similar to the support- 79. A tubular guide 90 vertically positioned is attached at its upper end to the support 89 in the plane of the cable 87 and is screwed to the base 41 of the device at its other end. Cable 87 after pass mg over the pulley 88 extends downwardly through the tubular guide 90-and is attached to a counter-weight 91 asclearly indicated in Figure 1. The mode ott attachnjient of said cable 87 to counter-weight91 can best be seen in Figure 8. Counter-weight 91 is formed hollow at 92 and is provided with an inwardly extending flange 93 leaving an opening 94: in the upper portion thereof through which the cable .87 may extend. Cable 87 passes through the opening 9 1 and into the hollow portion 92 ot' the counterweight 91 where said cable is attached to a head 95 adapted to engage the'underside ot the inwardly turned flange 93 when said counter-weight is hanging freely. When, however, this counter-weight is raised for a purpose to be later explained, said head 95 slides within the same without causing the cable 87 to be bent or crumpled. When the counter-weight 91 is permit-ted to hang on said head 95 this weight acts with the cable 87 and the arm 80 to draw bar 66 and the valve member d7 attached thereto into the position indicated in-Figure 3, causing the liquid to flow into the cylinder :21. lVhen, however, counter-weight 91 is raised so that flange 93 is free from head 95 and whenshoulder 7 7 is disengaged from the projection 78 valve member 17gis again slid into the position shown in Figure 1 by means of the coil spring 62.

In the normal position of the device counter-weight9l is hanging'as indicated in Figure 1 with the flange 93 resting on'head 95 so that the full weight of the same is exerted upon the arm 80. To hold valve member 17 in the position'shown in Figure 1 against the action of this weight, I employ a device est shown in Figures 4 and 6 which comprises-a dog 96 formed integralwith thedepending lever 97. This dog and lever are pivoted between two parallel tongues 98 formed on the underside of the arm 71 of bracket 7:2, said dog being positioned so as to engage a notch 99 formed onthe under-- side of bar 66. In the position of the parts as shown in Figure 4t which corresponds to that indicated in Figure 1, dog 96 is in engagement with notch 99 and in this position holds said bar 66 and the valve member 17 from movement against'the counter-weight 91 with the valve ports positioned relative to one another as indicated in said Figure 1. When the depending lever 97 is in normalposition it hangs substantially vertically down-' ward and when swung towards the right, the extreme end of dog 96 is thrown downwardlyaway from the notch 99' so that as said lever takes the position indicated in Figure 5 said dog is almost freed from engagement with the notch 99 and atter said arm is'swung still farther as indicated in Figure 3, said dog is completely freed and the bar 66 with the valve member 17 is caused to he slid to the rightto reversethe relation of the valve ports asfbetore specified. To prevent the notch portion 99 of bar 66 from following the dog 96 as thesame is swung downwardly, said bar-istormed at 100 with an inclined face adapted to engage the upper portion 101 of the protrusions 7 6. When the dog 96 is disengaged tromnotch 99 bar 66 slides along. the surtace 101 until the shoulder 77" arrives at a position opposite the ends o't said-protrus1 ons 78. A. fiat spring 102 screwed to bracket '72 by screws 103 normally presses downwardly upon the upper surface of bar 66 at 104. Thls spr ng permits of a sliding movement of the bar and also permits the same to be raised as the surface 100 slides along the upper portion 101 oi? the projection 7 8. and when said shoulder 77 reaches the atorementioned position relative to projection 7 8 this spring causes the bar 66 to drop downwardly andcauses said shoulder to be seated against towards the right until the ports 52 register.,

The means for operating the valve mechanism and for releasing the bar 66 comprises a plurality of depending rods 105, 106 and 107 which areall pivoted to the bar 66 with a single pin 108, two of these rods being positioned on one side and one on the other side of said bar. Each of the rods 107, 106 and is associated with a separate portion of the coin actuating mechanism 29 in a manner to be later described and controls the amount of liquid discharged into the cylinder 21. Each of-these'levers is hence arranged to be rendered operable by the insertion of coins of different denominations into the coin actuating mechanism whereby different amounts of liquid can be secured from the device. by the insertion of the proper coin. These rods normally hang downwardly in a vertical position and are adapted to engage a pin 109 secured to an arm 110 extending outwardly at right angles from the extreme end of the depending lever 97. Each of the rods 105 106 and 107 are adapted to be swung inward- 1y by means of the coin actuating mechanism 29 when the coin has been inserted in the same to the position shown in Figure 3. In swinging any of these rods inwardly the lever 97 is caused to follow along with said rodmeans of the pin 109 which is adapted to slide along any of the edges of said rods. As this lever 97 is swung the dog 96 is withdrawn away from its seat in the notch 99 in bar 66 causing the same to be released "from engagement therewith. As soon as said dog releases bar 66 the same together with the valve member 4L7 is drawn inwardly by means of the counter-weight 91 and the cable 87 so that the ports 52 and 50 register with one another, said bar 66 locking itself by means of the shoulder 77 and projection 78 as before specified. In this position of the various parts the liquid to be dispensed flows through pipe 23 through port 50 and the port 52 and into the interior of the cylinder 21 raising the piston 22 and filling the space below said piston and the casting 24 with the liquid. As the piston 22 rises, piston rod 31 follows with it and simultaneously raises three fingers 111, 112 and 113 all mounted on it in a manner to be presently described. These fingers are so disposed as to be positioned in the paths of the ends of the rods 105, 106 and 107 when the rods are operated into the position as illustrated by the rod 105 in Figure 3. It hence follows that when any of these rods are in said position the corresponding fingers 111, 112, and 113 will engage the end of said rod and force the same upwardly. At the same time the counter-Weight 91 is also raised so that it fails to act upon arm 80 by a device which will be presently explained. If any of the fingers 111, 112 and 113 raise its corresponding rod 105, 106 or 107 the bar 66 1s oscillated on the pivot 67 against the action of spring 102, which causes the shoulder 77 to be raised above its corresponding seat against the projection 78. This leaves the said bar 66 and the valve member 47 free to be forced back into their normal position by means of the spring 62 acting against the end of said valve member. In this position of the various parts valve member A7 has again taken the position shown in Figure 1 1n whlch the liquid supplied to the cylinder 21 is cut off whereas communication with the hose 27 and said cylinder is effected. \Vhen the spring controlled handle of the faucet or valve 28 is operated to cause the flow of liquid through the same the weight of the piston 22 forces the liquid from cylinder 21 through the ports 51 and. 53 and through the hose 27 and valve 28 and into the desired receptacle into which it is desired to have the liquid dis-' charged. This flow continues until the piston reaches the position shown in Figure 1 when all of the liquid within said cylinder 21 has been emptied. This leaves the device again in the normal inoperative position with the parts so arranged as to be ready to pass through another cycle of operations.

The device for rendering the counterweight 91 inactive is best shown in Figure 2. The lower end of the piston rod 31 is screwed into a boss 114lformed on a horizontal arm 115 which has a downwardly extending depending member 116. On the lower end of memher 116 is formed an arm 117 which extends parallel to and immediately below the horizontal arm 115. On each of the arms 115 and 117 is formed a pair of rearwardly extending lugs 127 all of which are slidably mounted on a pair of vertical guides 128 and 141. These guides are secured at their upper ends to a head 129 fastened on the angle support 89. At their lower ends said guides are threaded and provided with two nuts 130 and 131 by means of which said guides are bolted to the lower base member 41 of the device. These guides and the aforementioned portions 127 ofthe member attached to piston rod 31 serve to guide the vertical movement of said member and the parts attached there-- to as the piston travels up and down within the cylinder 21. On the end of the portion 127 of arm 117 is provided a finger 132 which extends through a horizontal slot 133 formed on the rear of the guide 90 housing the count-er weight 91. This finger 132 lies normally a short distance below the extreme end 134 of said counter-weight but as soon as the piston is raised engages the underside of said counter-weight and lifts the same relative to the casing 90 and the cable 87 as shown in Figure 8, causing the weight of said counter-weight to be removed from the head 95 secured to cable 87 and thereby removing the force exerted upon arm 80 tending to cause valve member 47 to be moved against the action of spring 62. In this manner it can be readily comprehended that when any of the rods 105, 106 and 107 engage any of the fingers 111, 112, or 113 and raise bar 66 that the spring 62 is free to act upon the end of the valve 47 to force the said valve member and the bar 66 attached thereto back into the position shown in Figure 1. When the liquid has been completely discharged from cylinder 21 and the device has again resumed its normal position as shown in Figure 1 said counter-weight 91 again engages the head 95 and exerts the force upon the lever 80 so that when the depending rods 105, 106 and 107 are again actu ated said counter-weight is able to act against the action of spring 62 to open the passagewayv from the pipe 23 to the cylinder 21.

As before stated the various rods 105, 106 and 107 are adaptedto be actuated by the insertion of coins of different denominations into the coin actuating mechanism 29 controlling the amount of liquid allowed to flow into the cylinder 21. The device for supporting the coacting fingers 111, 112, and 113 and for adjusting the same so as to secure the required. amount of liquid into the said cylinder is best shown in Figures 1 and 2. This portion of the invention is mounted on the two arms 115 and 117 and comprises three rods 118, 119 and 120 which are journaled in said members and extend completely through the lower member 117. Each of the fingers 111, 112 and 113 is threaded and is adapted to screw upon the respective rods 118, 119 and 120 and is hence supported on said rods as clearly shown in Figures 1 and 2. These fingers furthermore have rearwardly extending portions-124 which are adapted to slide upon a. single veri meant tical rod 125 arranged parallel to the threaded rods 118, 119 and and firmly secured between the arms 115 and 117. By means of portions 124; and rod said fingers are caused to be advanced along the respective supporting threaded rods 118, 119 and 120 without rotating upon the same thereby causing the ends of said fingers to travel in vertical lines in the direct paths of travel of the previously mentioned rods 105, 106 and 107 which are bent over as clearly shown in Fig ure 6 so as to lie in the path of travel thereof. Each of the rods 118, 119 and 120 pass through the arm 117 and carry a collar 126, so that these collars 126 of each of the rods 11.8, 119 and 120 set upon the' arm 117. The protrusions of said rod below the arm 117 have at tached to them spur gears 121, 122, and 123 respectively. The gear 121 is twice the size of the gear 122 and meshes with it. The gear 122 is twice the size of gear 123. and meshes with that. As these gears are rotated rod 118 is caused to rotate twice as fast as rod 119 and four times as fast as 120. For simultaneously operating the rods 118, 119 and 120 I employ a shaft which has a small spur gear 136 secured to one end of it and is adapted to mesh with the large spur gear 121 fastened to the lower end of rod 118. The other end of shaft 135 which is journaled in the arm 117 has mounted on it a hand wheel 188 by means of which said shaft and the corresponding, gears operated thereby are adapted to be rotated. In theparti cular form of my invention shown in the drawings I find it convenient to employ three coins, a quarter, a halt dollar, and a dollar to be used. in operating the mechanism. 107 are all formed of the same length it becomes evident thatinasmuch as the flow of liquid into the cylinder 21 is proportionalto the vertical travel of the fingers 111, 112 and 113 that said fingers must be caused to travel in the ratio 1 2 4: to discharge an amount of liquid proportional to the values of the coins insertaible in the device. It can. be further comprehended that as the base price of the liquid dispensed changes that the amount of liquid desired to be discharged into the cylin der 21 must vary accordingly. It is towards this end that the cooperating gears 121, 122 and 123 are provided, When hand wheel 138 is rotated all of the rods 118,119 and 120 are simultaneously rotated, rod 119 being turned.

twice as fast as rod 118, rod 120 being turned four times as fast as rod 118. In order to make all of the fingers 111, 112 and 113 travel simultaneously either upwardly or downwardly as said hand wheel 138 i's rotated I thread the two rods 118 and 120 with right hand threads and the middle rod 119 with left hand threads. To inform the person adjusting this portion of the invention of the positions of fingers 111, 112 and 113 corresponding with the fluctuations in the base s'the rods 105, 106 and price of the liquid dispensedI provide a pointer 139 formed on the finger 113 which is adapted to slide along a graduated scale 140 formed on the depending member 116 secured to portions 115 and 117 of this device- This scale 1&0 is calibrated and marked in dollars and cents so as to indicate the unit price per gallon of the liquid dispensed. In the position shown in Figure 2 the pointer 189 is positioned opposite twenty-five cents indicating that the unit price per gallon oi the liquid dispensed is twenty-five cents and that by the insertion of e ther the quarter, half dollar or dollar into the appropriate coin actuating mechanism a corresponding volume of liquid will be dispensed for the respective amount of money inserted at the rate per gallon indicated on this scale.

The coin actuating mechanism of myin vention comprlses three distinct coln con trolled devices which act independently on each of the previously mentioned depending rods 105, 106'and 107 which are supportedon the bar 66 operating the valve member 17.

These'coin actuating devices are identical in construction and operation, differing only in such dimensions as are necessary to cause them to function properly with the size of coin for which they are to be used. In Figure 6 three such mechanisms are employed indicated'at 14:2, 143 and 14 1, each of which has a separate coin receiving member 145 and a coin delivering chute 146 all of which later.

discharge the coins into a separate coin re ceptacle 147 which is best shown in Figure 3. Thiscoin receptacle is formed with an ei'iterior flange 148 which extends around the same and which is seated on the edge of the casing 20 oiithe entire device around an opening 1 19 :Eormed in-said casing. This receptacle is further provided with adownwar'dly extending catch150 adapted to engage the inner surface of the casing'20 and is also provided at its upper end with a lock 151 having;

a latch bar 1152 adapted to be turned. so as to engage theyinner side or the casing 20 on the side ot opening 149 opposite to the catch memher 150. By means of these devices the entire receptacle 147, which extends within said casing 20 -.1s adapted to be held in place to completely enclose the same within the said cas ng 20. If des red the whole casing may be removed and the coins removed therefrom iio through-any of the openings 152 through.

which the coin discharging chute extends or if desired a hinged or removable door 153- mounted on the exterior or receptacle 1 17' and held in place'thereon by means of a lock 154 j may be used, permitting the receptacle to re main in place on the machine.

Inasmuch as the various coin actuating mechanisms 1 12, 143 and 1 14 are identical in: construction and operation only tliatindicatedat 1&4 which isshdwh infcross' section i'n the various" figures of the drawings will be described in detail. As best shown in Figure 3, the coin receiving member extends through the outer casing 20 of the machine and is provided with a slot in which a suitable coin is adapted to be inserted. This member 145 inclines downwardly at an angle from the receiving slot 155 to an enlarged portion 156 having a relatively fiat bottom 157 on which the coin is adapted to lie in a horiaontal position when the same arrives therein, which is clearly shown in Figure 4 at 168. The various coin actuating mechanisms 142, 143, and 144 are supported within the casing 20 on the flat portions 157 of the members 145 by means of an angle iron support 159 which is secured to the walls of the casing 20 to which said flat members 157 are bolted. Slidably mounted in a journal 158 secured to the casing 20 and in another journal 160 mounted on the angle iron support 159 is a horizontally positioned plunger 161 preferably of square cross section. This plunger has secured to it a collar 162 and is adapted to be moved against the action of a compression coil spring 163 1nounted on said plunger which is seated between the journal 160 and said collar 162. As noted in the figures plunger 161 is provided at its outer extended end with a push button 164 and at its inwardly extending end with a head 165 formed with an inclined portion 166 which normally lies back of the rear wall 167 of the enlarged portion 156 of the coin receiv ing member 145. When the coin 168 is discharged into the chamber formed at 156 said coin normally falls on the member 157 to the right of the supporting head 165 of plunger 161. Upon thrusting button 164 inwardly head 165 is caused to engage the edge of coin 168 and to slide the same towards the right, against the action of a dog 169 pivoted to the underside of the bottom 157 at 170. This dog has a downwardly extending arm 171 which operates against a compression coil spring 172 seated between said arm and the angle support 159. Said dog is further provided with an inclined operating end 173 which extends upwardly beyond the end of the bottom 1.57 and closes the passz'tge-way between an upper roof member 174 connected to the coin receiving member 145 and the said bottom 157. As the plunger 161 is thrust inwardly said coin 168 is forced inwardly between the roof member 174 and between bottom 157 depressing the dog 169, said coin gradually assuming the position indicated in Figure 5. In the normal position of lever 105 said lever hangs immediately to the right of the operating end 17 3 of dog 169 and passes through a slot 175 formed in the roof member 174. As the coin 168 is forced inwardly the edge of said coin engages the portion of rod 105 within the coin actuated mechanism and swings said rod to the right as indicated in Figure 5. Immediately beyond the bottom 157 a flat table 176 which is pivoted at 177 to a depending lug 178 formed on the underside of the roof 174. This table is normally held spaced from the roof 175 a distance sufficient to permit the insertion of the coin 168 between said roof and table by means of a compression coil spring 179 positioned between an upwardly extending lug 180 formed on the root member 174 which lug is bolted to an angle iron support 181 extending across the casing 20 and between a rearwardly extending arm 182 formed integral with the portion of the table 17 6. Said table is also formed slotted at 183 to permit the operation of the rod 105 through the same as clearly indicated in Figure 6. As the coin is thrust into the device by the plunger 161 said coin forces the operating end 17 3 of dog 169 downward, passing over said dog and into the space between the table 176 and the roof 174 as indicated in Figure 5, towards the right. I Vhen said plunger 161 has been thrust its entire length into the coin actuating mechanism the edge of coin 168 passes the point 17 3 of dog 169, which is the extreme position, said coin may occupy within this portion of the mechanism. In order to hold the rod 105 in its operating position until the fingers 111 can engage the end thereof it becomes essential to cause said coin 168 to remain within the device. In the event that the plunger 161 is held inwardly said coin naturally cannot be ejected. However, in the event that said plunger is released upon having first projected the same inwardly the dog 169 serves to hold the coin within the same. As soon as the head 165 of said plunger passes the point 173 of dog 169. The 169 through the action, of the spring 17 2, is drawn upward so as to prevent the movement towards the left of the coin. In this manner the coin is clearly held in its engaging position with rod 105 until. the same is desired to be released. when the required amount of liquid has been discharged into the cylinder 21 as beiore specified, fingers 111 engage the end. of rod 105 which lifts said rod and the bar 66 thereby permitting spring 62 to draw the valve member 47 into normal position and cut off the supply of liquid into the cylinder. At the same time that this rod 105 rises, a lug 184 formed on said rod engages a cam surface 185 formed on the underside of lever arm 182 which causes the table 176 to be swung downwardly clearly shown in Figure 3, permitting the coin 168 to'slide downwardly from its position shown in dotted lines at 186 in said Figure 3 following along the top of said table and the upper surface 187 of the coin delivering men'iber 146 and into the receptacle 147. The downward movement of coin 168 is facilitated by the inclined lower surface 188 of the operating end 173 of dog 169 which tends to throw the coin downward upon the release of the pressure of table 176 against tne underside of the com. For re turning rod 105 back to its normal position I employ a small counter-Weight 189 secured to a cable 190 which passes over a pulley 191 mounted on an angular support 192 secured to the casing 20. This cable 190 is attached to the rod 105 so that when said table 176 is depressed and the coin 168 released that said weight draws the rod 105 back to its normal position. It can be seen that the coin controlling mechanism is of such a nature as to hold the parts in their operable positions for the necessary time required and the proper functioning of the same to permit the low of the required amount of liquid intothe cylinder 21 and to'cut off this -flow when the predetermined measured amount of liquid has been discharged therein.

, In place of the valve mechanism shown in Figure 1, I have provided an alternate form of valve mechanism which is clearly indicated in Figure 9. In this form of the invention the casting 44 is dispensed with and another casting 193 is provided which has a single port 194 communicating with the space between the underside of the piston 22 and the cylinder 21. WVithin the casting 193 is formed two valve chambers 195 and 196 which communicate directly with the previously men tioned discharge hose connection 56 and the supply pipe connection 60 as indicated in the drawings. WVithin'these valve chambers are slidably mounted two reciprocating valves 197 and 198 which are respectively adapted to control the flow of liquid from the pipe '60 to the port 1% or from said port to the pipe 56.

These sliding valves are provided with stems 199 and 200 which extend through the walls of casting 193 and which are providedwith a lever 201 pivoted to the ends thereof. The lever 201 is pivotally connected at its center to a standard 202 mounted on casting 193. A compression coil spring 203 acting between the casting 193 and the end of the valve stem 199 serves to hold the valves in the respective positions shown in Figure 9 in which coinmu nication between inlet pipe 60 and the cylinder 21 is cut oil and in which an outlet for any liquid included within the said c ylinder is obtained through the pipe 56. The previously mention-ed bar 66 is in this instance formed with a downwardly inclined arm 204 which is pivoted to the point of connection of the lever 201 to the valve stem 199. For this device the operation is identical with that of the other form of the invention. When bar 66 is released the counter-weight 91 forces the said bar to theright against theaction of spring 203 opening valve '198' and closing valve 197 thus. making the operation of the device identical with that shown in Figure 1.

Another alternate form of valve mech anism is shown in Fig. 10 which is similar to that shown in. Figure 1'. .In this form casting 44 is again dispensed with and a casting 205 substituted in place thereof. This casting is provided with a conical bore 206 in which is rotatably' mounted a conical valve member 207. A single port 208 leads from the bore 206 into the space between piston 22 in the cylinder 21 in a manner similar to the device shown in Figure 9. -Th-e lower portion of casting 205 is formed with two ports 209 and 210 which communicate with the bore 206 and the respective pipes 56 and 60. A port 211 formed on valve member 207 is adapted at one end to communicate with either of the two ports 209 or 210, and at its other end at 212 is iformedenlarged to com municate at all times with the port 208 in through the extension 2040f bar 66 which is pivoted to the arm 215 at 216. The oper ation of this device is identical with that of either oi the other forms of the invention and simply shows a different form of valve operating mechanism which may be'einployed with the invention.

The advantages of my invention are manifest. A predetermined and accurately measured amount of liquid is discharged into the cylinder so that the buyer of the liquid is positive of receiving full measure. The means for controlling the flow of liquid to this cylinder are, positive in action so that when the device has once been. set positive action and accurate measurements are assured.- The entire devlce 1s absolutely automatic so that upon the insertion of the coin and pressure of the button provided for that purpose the liquid is caused to flow at the desire of the purchaser into any receptacle in which he wishes to direct it. The entire mechanism is operated through the pressure of the liquid inthe reservoir in which liquid is stored, thereby eliminating all auxiliary operating devices for measuring and controlling the iiow of the liquid. All electrical devices being dispensed with my improved liquid dispensing machine is highly suitable. for. the dispensing of gasolineand other combustible liquids in which the employment of electricity for controlling and operating the same would be rendered dangerous due to the possible explosion which might be incurred in the use thereot.
